The following are important for shooting under water.

1.Plan what you want to shoot before getting into the water. Visualize it, see it even before you make a splash.

2.Make sure your lens and port is clean, check how much tape you have left and make sure your batteries have a full charge. Verify full operation by working all essential controls: on/off, zoom, record, focus lock, white balance. As soon as you get in the water and set up your system, don’t forget to look at your port and wave your hand in front of it dislodging any bubbles or particles from the surface of the port.

3.Look up and figure out where the sun is. Shoot with the sun at your back unless you purposely plan a silhouette shot. Silhouettes can be extraordinarily dramatic in the right circumstances with enough distance between the camera, subject and sun, yet the golden ruling in lighting keeps the sun at your back. Compose your shot before hitting record, use the rule of thirds and ensure you leave “fish” room for your subjects. You want to hold the system as steady as possible, use a tripod for macro shots. Think of the camera angle and what is pleasing to your eye. Avoid shooting down at subjects unless you are going for a specific look.

4.Compose, Record, Stop, Move. Compose, Record, Stop, Move. Think of your edit. How are you going to piece your shots together? 10Wide, Medium, Close-up. Wide, Medium, Close-up. Think of your edit. How are you going to piece your shots together?

5.Shoot 4-6 seconds of handles on the front and end of every shot.You want to make sure your camera is rolling before the action takes place and have extra on the end of your clip when action is finished.

6.Video is all about motion, so think about how you are going to get motion from your ocean. You can allow your subject to swim in and out of your shots or you can create the motion by swimming with the camera. You want to combine reveals, tracking and over the shoulder shots to completely tell your story and make your life easy at the edit station. Try and avoid the subject just popping up in the middle of the frame! Start with a pan left or right, or a tilt up or down that will introduce your subject to the frame.

7.Take the last 5 minutes of the dive to try something new! Shoot 30 seconds of a wild camera angle, pan or manual exposure control. Watching these tests might inspire your next creative technique.

8.Once you exit the water, take care of your equipment and dry off your port to avoid water stains. Take the time to review and log your tape everyday! This way you know immediately how to make corrections or if your day was successful!

Thanks for the tips! I have only attempted underwater video twice without much luck. I think I'll give it another go if I ever get the chance again. I don't have my own equipment, I borrowed it from a friend.

I spent a month in Key Largo studying underwater photo with Unv. of Miami. It was one of the best months of my life. There is nothing like capturing that perfect image. It is also a great way to improve your scuba diving skills since you really have to be in control of you buoyancy at all times.

Really useful post! Thank you!
